1. A breathing circuit connector for coupling the output from an anesthesiology machine to the open input end of an endotracheal tube connector, comprising in combination:

  • (a) a body of relatively rigid material, said body having a hollow cylindrical input section adapted for coupling to the output of the anesthesiology machine, said body further having a hollow cylindrical output section adapted for coupling to the open input end of the endotracheal tube connector;

    (b) a passageway situated within said body and extending between and connecting said hollow cylindrical input and output sections for providing fluid coupling therebetween;

    (c) a first smooth and continuous cylindrical bore portion of uniform diameter situated within and forming an integral part of said hollow cylindrical output section, said first cylindrical bore portion having one end adjacent the output end of said hollow cylindrical output section and having a second end situated within said hollow cylindrical output section; and

    (d) a second smooth and continuous cylindrical bore portion of uniform diameter situated within and forming an integral part of said hollow cylindrical output section, said second cylindrical bore portion being coaxial with said first cylindrical bore portion and having one end adjacent the second end of said first cylindrical bore portion, said second cylindrical bore portion having a second end situated internally of said hollow cylindrical output section, the diameter of said first cylindrical bore portion being slightly larger than the diameter of said second cylindrical bore portion the difference between the diameter of said first bore portion and the diameter of said second bore portion being approximately 0.05 to 0.1 millimeter.
